Sovereignty concerns the choices you can actually exercise.
The European Commission describes technological sovereignty in terms of independent action and control over technology, data and infrastructure.[S1] For an AI service, we use a narrower working explanation: can you decide how it is used, check its dependencies and change course when necessary? A hosting address answers only part of that question.
Consider our invented support-draft service. Its specification says that it runs in Frankfurt. That assumption alone tells the team nothing about administrator access, continued operation or moving the workflow elsewhere.[S3]
Invented example · no sovereignty assessment
A hosting location leaves three control questions open.
AI drafts a reply to an internal support request
The missing evidence belongs beside the location claim.
For this draft, we propose three follow-up checks. Ask who can read the request and change access, which team could maintain the service without the present supplier’s support, and which data, instructions and integrations could be transferred and retested. Record the evidence and the person responsible for each unresolved question.
The Commission’s cloud-procurement guidance separates data, operational and technological concerns and examines dependencies across technical layers and suppliers.[S2] Our small inventory is an introduction to those distinctions, not the Commission’s assessment, a certificate or a legal conclusion. Neither a European address nor a second model establishes all of them.
Choose the control you need for one real workflow.
Start with a task your team already runs. Name its model version and operator. Put verified facts and open questions in separate columns, then decide which gaps must be resolved before use. Some dependencies may be acceptable for that task; others may require a different design. Keep contractual and legal questions with the people qualified to review them.
If the practical concern is continuing work when a provider fails, use our second-provider comparison. It addresses that narrower decision. We have not measured replacement time or cost, or assessed legal suitability.
